The second liner ring here refers to the liner ring adjacent to the lowermost liner ring.

As shown in fig. 2, in order to disengage one of the liner rings from interference with the other liner ring, the corrugated structure of the liner ring may be utilized to press both sides of the liner ring, so that the pressed portion of the liner ring is contracted inward in the radial direction of the liner ring, and the non-pressed portions are expanded outward in the radial direction, thereby primarily disengaging interference between the pressed liner ring and the other liner ring; the extruded liner ring forms a protruding part on two sides which are not extruded; in the horizontal direction, a certain gap exists between the extruded lining ring and other lining rings, the clamping jaw can extend into the gap and clamp the protruding part, so that other lining rings are lifted, the interference between the extruded lining ring and other lining rings is thoroughly eliminated, and the material distribution is completed.

The lining rings can be clamped only by extrusion, and if a single lining ring is attempted to be clamped by directly using the clamping assembly, because the lining rings are thin, the control precision of the clamping jaws is limited, a plurality of lining rings can be easily clamped, and material distribution cannot be realized.

As shown in fig. 5, 6, 7 and 10, the cross section of the special-shaped plate 210 is a shape remaining after two arcs symmetrically arranged are cut out in a circular shape, and the special-shaped plate is provided with a circular arc surface 211 facing to two ends of the platform and flat surfaces 212 facing to two sides of the platform; the extrusion plate extrudes the part of the bottommost lining ring corresponding to the flat surface, so that the part of the bottommost lining ring corresponding to the arc surface expands outwards to form the protruding part 11.

The special-shaped plate is suspended above the platform, a certain gap is formed between the special-shaped plate and the platform, and the height of the gap is larger than that of one lining ring, so that the lining ring can be conveyed to other processes after the lining ring is clamped by the clamping assembly; however, the gap needs to be smaller than the height of the two lining rings, when the clamping jaws clamp the lowest layer of lining rings and transport the lining rings to other stations, the blanking plate is needed to limit the second layer of lining rings, so that the second layer of lining rings are prevented from being dislocated due to the friction force between the lowest layer of lining rings and the second layer of lining rings, and the subsequent production is prevented from being influenced.

As shown in fig. 5 to 6, the profile of the pressing plate 330 for pressing one surface of the liner ring is divided into a straight line segment 331, a first arc line 332 and a second arc line 333 in sequence, the bending direction of the first arc line is opposite to that of the second arc line, the bending direction of the first arc line faces the profiled plate 210, the intersection point a of the straight line segment 331 and the first arc line 332, and the connecting line of the points a of the pressing plates at two sides divides the cross section of the profiled plate into two parts with equal area; the radius of the first arc line is the same as that of the lining ring; as shown in fig. 6, when viewed from the top view of the pressing plate, the pressing plate presses the backing ring, and when the first arc line 332 comes into contact with the backing ring, the second arc line is spaced from the profiled plate by a distance in the horizontal direction; the pressing plate continues to press the bushing ring, so that one side of the bushing ring, which is far away from the second arc line, is staggered with the corresponding arc surface 211 to form the protruding part 11.

If the lining ring is pressed in a common mode, two sides of the lining ring are contracted, two ends of the lining ring are expanded outwards, but the distance between the two expanded ends is insufficient, so that clamping jaws are difficult to accommodate, and clamping cannot be achieved.

One side of the extrusion plate, which is used for extruding the lining ring, is an extrusion surface, the extrusion surface of the extrusion plate adopts a multi-section line arrangement, the intersection point of the straight line section and the first arc line is a point A, the intersection point of the first arc line and the second arc line is a point B, and on the cross section of the special-shaped plate, the circle center of the arc surface corresponding to the arc line is O; a connecting line AA of the points A on the extrusion plates at the two sides divides the cross section of the special-shaped plate into two parts with equal areas, namely the connecting line AA passes through the point O; the vertex of the special-shaped plate, which is closest to the second arc line, is K, and a line segment KC is made through the K point, so that the KC is parallel to the AA, and the KC is crossed with the second arc line at the C point.
